Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

These are gadget huts. It's made of techno-hopium material.

They'll want money to do this in some poor rural area in a place where they can hardly name the native language. They think this will help poor people, but ignore the part where humans have always built shelters. If they fail to transfer the technology and know-how, then this technology is, over time, totally useless. And they will fail because such tech is usually patented and protected by IP laws.

If they try to sell this in the richer parts of the World, all they will do is make the environment and climate worse by promoting more suburban sprawl.

Yep. The cheaper and easier solution to extreme housing issues is a few pallets of bricks and some mortar. This company is on a marketing campaign to try to get people in rich countries to get excited about buzzwords so they can get funding.

The ones in Texas are built of a "high performance polymer concrete", so probably including cement and contributing to climate change. They appear to be single storey as well.
